As a tool for cutting garlic species, conventional scissors, sickle, knife, etc. have been used in the past, but if you keep working with ordinary scissors, your hand hurts and you cannot continue working for a long time. Because you have to work in an uncomfortable posture to bend the waist for a long time, there was a problem that it was difficult to work for a long time due to pain in the lower back. In order to solve these problems, the present invention is to form the blade of the garlic seed cutting knife on both sides, and to adjust the angle of the blade so that the shape of the garlic seed cutting knife in the shape of sickle or knife Fixed to enable use. When using double-sided knife in the form of a sickle, when the blade needs to be replaced because the blade is dull, the double-sided blade is rotated by 180 degrees to fix the double-sided blade. .
